The weirdest part is I didn't get any text messages while I was sleeping. Maybe I should try uninstalling and reinstalling and see what happensDid you get a message and have LED blinking on all night? And does textplus have repeat notifications that turn the screen on? That could have caused it.
Thank you for your suggestion. I did as you said after uninstalling and reinstalling the app. I'll be curious to see if it happens again or if it goes back to normalMaybe the app got stuck in some sync process. You could try force stop in settings - apps, clear cache and then restart the phone.
